Tom Archers blog on ReadyBoost is by far the best info out there.
My experience is:
ReadyBoost's test to check to see if your flash drive is fast enough sucks.
I hope they put out a utilitiy that shows how close your drive is.
Why do I say the test sucks, and not my drive...welllll.. I have a PNY
Attache 4 GB drive. I have used it as a ReadyBoost drive successfully on 2
machines, BUT NOT EVERY TIME. This last time, it took me 6 plug-unplug
cycles, changing through 4 USB ports, and finally it worked when at the end
of a USB extention cable, on a port that it had not worked on direct 5 mins
before.
On my other machine I had to plug-unplug 3 times, and I reformatted it
twice.
On my laptop(where it would do the most good) it has never been tested as
successfull.
I have 4GB of Ram on this machine, and Vista recommends a setting of 3830 MB
for it. ReadyBoost compresses the data, so that is about 7.5 GB of data on
the drive.
As mentioned, this is not 'added" to Real Ram, nor is it added to Virtual
Memory..As I understand it, it is used as a write through cache of the
Virtual memory cache(and SuperFetch cache) which reside on your hard drive,
thus speeding up loading of recent/common apps(SuperFetch) and decreasing
hard disk access for other VM tasks.
I hope they get a testing tool(so I can figure out the Laptop Issue) and
some best practices info to try to figure out why it will pass the test 1 in
5 times or so...By the way, once it tests as fast enough, it will keep
working through restarts, etc.
